Run ruby script in background without using screen

Question

I have a two scripts in the Rails environment which have to run 24/7. I'm working on a remote server, so I need to start the scripts using ssh, which means I need to keep the ssh windows open all the time.

I'm searching for a simple way to run these scripts in the background so they aren't canceled as soon as I close the ssh connection.

I don't want to use screen. I think there must be simpler way to handle this. Isn't there?

Answer 1

I think the most basic solution would be nohup:

nohup myscript &> /dev/null &

Answer 2

You can disown a script:

 ruby script.rb &!

STDOUT/STDERR are still attached to the current shell, but the ruby process isn't a child of the shell anymore, so it won't get killed if you close the terminal.

Answer 3

Check Daemons. It's a toolkit for converting a script to a controllable daemon.

Answer 4

You can use

• runit
• supervisord

For daemonizing

Or some ruby stuff: https://www.ruby-toolbox.com/#Background_Processing for background processing
